Classic Open-Faced Burger with Caramelized Onions

Method

1. Preheat a skillet over medium heat and add sliced onions. Cook until caramelized, about 15 minutes.
2. In the same skillet, cook the grass-fed beef until browned and cooked through.
3. Toast the wholemeal bun lightly.
4. Assemble the burger by placing the beef on the bun, adding caramelized onions, lettuce, tomato, and fruit chutney.
5. Finish with a drizzle of mustard and serve immediately.
6. For whole cuts, check a minimum internal temperature of 63°C (145°F), then rest for at least 3 minutes before serving.
